Hi there, welcome to LabEx! In this first lab, you'll learn the classic "Hello, World!" program in Matplotlib.

Click the Continue button below to start the lab.

Hello Matplotlib

Let's start by importing the Matplotlib library. Open a new terminal and type:

python3

This will open a Python interpreter. Now, let's import the Matplotlib library:

import matplotlib.pyplot as plt

Now, let's create a NumPy array with 1000 values between 0 and 2π:

import numpy as np
x = np.linspace(0, 2*np.pi, 1000)

Now, let's create a plot and show it:

plt.plot(x, np.sin(x))
plt.show()
